Yes, these are Arion discs.  You will also realise from my book that
these are the same as Britannia.  They are rare and not compatible with
[movements by] any other maker.

The whole idea of writing my book was to help people identify over
1,450 different disc musical box models and 350+ types of discs...

Unfortunately this make / size is not made new by anyone at the moment;
this week alone I have had three enquiries for these discs.
